The AirTAC GFR400C10LJC2GK AirTAC Filter Regulator G3/8 Low-Pressure is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has See datasheet ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR400C10LJC2GK is a GFR400-series filter regulator: water and particulate removal plus downstream pressure regulation combined in one body. This configuration is built for a G3/8 (3/8 inch) port with G (BSPP) thread, carries the standard 40 um filter element, and drains collected condensate by differential pressure. It is the low-pressure type, and its exact adjustment range is not published in the material we hold, so we confirm it on request. A round pressure gauge reading in psi is fitted, a reverse (check) valve is built in, and no mounting bracket is included (code J). The unit is rated for a maximum inlet pressure of 1.0 MPa (145 psi), operates from -5 to 70 C (non-freezing), and the polycarbonate (PC) bowl suits the 400 size.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and options that include automatic, manual or differential-pressure drains, a finer 5 um element (code W), embedded square or external round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so send us your application details and we will confirm sizing and datasheet figures on request before you order.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). Air must not freeze in the unit. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

Field order is size, port, drain, type, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

Feeds filtered, regulated air to the clamp and hold-down actuators on a panel press where the working setpoint sits below what a standard regulator covers, with the built-in check valve blocking reverse flow through the unit.
Mounted ahead of the cylinders and grippers that index bottles on a filling conveyor, removing water and 40 um particulates from shop air while the low-pressure regulator lets operators set a stable working pressure at the machine.
Supplies conditioned low-pressure air to a pilot plant or test rig, where the round psi gauge gives a clear local reading and the differential-pressure drain removes collected condensate as the unit works.
Pick the size by the port and air demand of your line: GFR units step through 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and this 400 unit sits at G3/8. Drain choice matters: this unit uses the differential-pressure drain (the default); automatic (A) and manual (M) versions are available if your duty suits them better. Filter grade is the standard 40 um here; specify code W for the 5 um element where finer air is needed. On gauges, this configuration carries a round gauge with a psi scale (C2); the embedded square gauge and MPa or bar scales are the alternatives. Thread is G (BSPP) as ordered - PT is the AirTAC standard and NPT is also an order option. No bracket is fitted (code J), so plan your mounting. One honest note before you commit: flow for this series is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR400 as curves, not as a single rated number, so we do not quote a figure here. Send us your inlet pressure, set pressure and expected air demand, and we will confirm the sizing against the datasheet curves on request.
C2 specifies the round pressure gauge fitted to this unit, reading in psi. The standard GFR configuration carries an embedded square gauge instead, and MPa or bar scales are available as alternatives - tell us your preference when ordering.
